Facing a Mirror

Use the following techniques if you wish to perform breast self-examination. Choose the method that is best for you.
Stand before a mirror and compare the breasts for differences in size, nipple inversion (turning in), bulging, or dimpling. Note any skin or nipple changes, such as a hard knot or nipple discharge.

Inspect your breasts in the following four steps:

With your arms at your sides

With your arms overhead

With your hands on hips - press firmly to flex your chest muscles.

Bend forward - inspect your breasts.

In these positions, your pectoral muscles are contracted, and a subtle dimpling of the skin may appear if a growing tumor has affected a ligament.
